digitalsmart

Digital Trak is a smart positioner and it is a loop powered instrument. As a control part of the pneumatic valve set, this item is widely used in petroleum, chemical, electric power, metallurgy, light industry and other fields of automation systems. DT Intelligent Electro-pneumatic valve Positioner accepts the 4/20 mA valve setting signal from the control system. At the same time, it gets the actual valve signal through the location sensors; the two signals are compared by control software in order to control the feeding and exhaust of the gas to actuator and to drive the valve to reach set point. This product is based on microprocessor technology. It can overcome friction and the imbalance power on the control valve well, and improve the response speed of control valve, which makes the position set rapidly and accurately.
